Aren't you are over-reacting?
Vingegaard and Roglic are 2 of the top 3 (with Pog) of what are a very good crop of Grand Tour riders with Kuss the best super-domestique currently in world cycling. Evanpoel might not be far behind, but he is behind on experience, form and age when it comes to a Grand Tour.
There's no surprise at their perfomance. Had they been 1-2 in GC or on any stages, no one would have raised an eyebrow.
On velogames, despite being in the same team (a red flag usually) Roglic and Vingegaard was the most popular GC pairing selection selected by 1,000s of armchair punters.
The Vuelta "surprise" was Kuss on the GC which came let's be clear came from his Stage 6 breakaway and an effort in the TT which he wouldn't normally push so hard on.
Has anyone heard why Evanpoel performed so poorly on Stage 13? That would be the big question mark for me. It turned the GC in to that 3 horse race between LJ riders.
On the day and following day no one offered an explanation and his management underlined it wasn't illness.
As for the rest, Landa is passed his best and his best was never good enough. Mas, Almeida and Thomas were the only other ones with the pedigree to suggest a potential podium if they put in a solid 3 weeks, but not one of them seemed in great form.
I have to say it's disappointing. I expected a great event, and whilst I enjoyed many of the stages, the overall was a done deal post Tourmalet.
